NGC has many, many, many more years experience. PCGS just started grading and attributing these in the past year. In all honesty, NGC makes a fair number of mistakes on Fuld number attributions, but most of those can be traced back to what the submitter listed the token as to begin with.
Based on what I have seen from the first couple hundred PCGS graded Conder tokens, I suspect that PCGS will be equally bad (or worse) at attributing exonumia (note, PCGS just started grading in the past 6 months to a year Conder tokens, so-called-dollars, many medals, civil war tokens, and several other types of exonumia that NGC has been grading and attributing for a good 15-20 years).
If you know what you're doing (which you do Dave), then NGC will likely just go with your Fuld numbers that you put on the form.
